Analysis of the wastewater treatment device for the damper tank of sewage pumping stations

The article presents a model range of an automated wastewater strainer developed on the basis of utility model “Device to perform primary wastewater treatment of suspended solids at sewage pumping stations”. The device is aimed at efficient mechanical treatment of domestic, storm and industrial effluents at sewage pumping stations and other objects of the water disposal system. The operating parameters of the device are designed based on the gradation of daily flow rates, volumetric solids content and operating conditions. The verification calculation of structural elements for strength and stiffness was carried out taking into account dynamic loads. The parameters of the actuators were determined the selection of gear motors was made.
